1. PHOTOSYNTHESIS
Autotrophic Process: Plants and plant-like organisms make their energy (glucose) from sunlight.
Stored as carbohydrate in their bodies.
6CO2 + 6H2O + sunlight  C6H12O6 + 6O2

2. Why is Photosynthesis important?
Makes organic molecules (glucose) out of inorganic materials (carbon dioxide and water).
It begins all food chains/webs. Thus all life is supported by this process.
It also makes oxygen gas!!

3. Photosynthesis-starts to ecological food webs!

4. Photo-synthesis
means "putting together with light."
Plants use sunlight to turn water and carbon dioxide into glucose. Glucose is a kind of sugar.
Plants use glucose as food for energy and as a building block for growing.
Autotrophs make glucose and heterotrophs are consumers of it.

5. Photosynthesis 6CO2 + 6H2O + energy  C6H12O6 + 6O2
Carbon dioxide + water glucose + oxygen
sunlight
absorbed by chlorophyll
6CO2 + 6H2O + energy  C6H12O6 + 6O2

6. Plants in Action Check it!
What is the process that uses the sun’s energy to make simple sugars?

7. Plant Cells

8. The photograph below is an elodea leaf X 400
The photograph below is an elodea leaf X 400. Individual cells are clearly visible. The tiny green structures within the cells are chloroplasts this is where photosynthesis happens.                                    

9. Chloroplasts make the sugars!

10. Leaves are green because they contain
Plants
Leaves are green because they contain
the pigment:
chlorophyll
Leaves have a large surface area to absorb as much light as possible
"Thanks for the Glucose!"

11. Chloroplasts make the oxygen too!

12. Stoma This opening how plants exchange gases. Check it
Stoma This opening how plants exchange gases! Check it! Can you name the two important gases that go in and out of the leaves?
Why are the stomata located on the underside of leaves?

13. PHOTOSYNTHESIS
Absorbing Light Energy to make chemical energy: glucose!
Pigments: Absorb different colors of white light (ROY G BIV)
Main pigment: Chlorophyll a
Accessory pigments: Chlorophyll b and Carotenoids
These pigments absorb all wavelengths (light) BUT green!

14. PHOTOSYNTHESIS Why do we see green?
Green color from white light reflected NOT absorbed
Chloroplast: organelle responsible for photosynthesis
Chlorophyll: located within Chloroplast
Green pigment

19. The end!
